I wouldn't say it's a convenient backpack. Especially with the price it has, I believe there are more convenient backpacks. The main issue is that it is narrow, resulting in very few things fitting besides the laptop. Even the pockets are narrow, especially the front one.

Perfect backpack, made from recycled materials. The quality is evident, and it is fully waterproof.
Only negative (4 stars): the available space for a few books or a laptop. There is no elasticity for much more. There are small internal pockets. The exterior with the zipper is quite narrow, just enough for keys and a phone. Recommended only for walks and carrying minimal items.

I bought this specific backpack for a fun trip. It is very elegant and beautiful. It is also extremely comfortable, with very good and completely waterproof straps. However, my average rating is based on two disadvantages. 1. The external waterproof material of the backpack is particularly vulnerable to friction, resulting in three visible scratches after the trip, despite regular use. 2. Its capacity is particularly limited because it has no elasticity. The additional pockets are decorative and cannot fit a water bottle. The front pocket is also so narrow that I had difficulty putting my hand in. I would recommend it for office use, computer, etc., but not for travel.
